Water TreatmentpH valueThe pH value of pool & spa water should generallybe between the slightly acidic value of 6.5 and theslightly basic value of 7.6. Due to the use of variouswater treatment chemicals as well as ambientenvironmental effects, pool owners have to determinethe pH of the water and correct the value asnecessary.DIsinfeCtionNowadays, pool owners can choose from arange of modern water treatment agents that areoften used in combination.These water treatment chemicals are onlyeffective within a limited pH range. Therefore inaddition to checking the concentration of the watertreatment chemicals, the owner/operator should also monitor the pH value of poolwater and adjust it if necessary.Rapid TestsMINITESTERThe MINITESTER with an interchangeable colourcomparison chart is a competitively priced starterunit with one measuring chamber for thedetermination of either chlorine, bromine, activeoxygen and the pH value.THREE-CHAMBER TESTERThe THREE-CHAMBER TESTER with an interchangeablecolour comparison chart is a competitivelypriced unit for the determination of disinfectantsand the pH value.POOLTESTERThe POOLTESTER allows simultaneous determinationof the most popular water treatment agentsand the pH value.POOLCHECKThe term "balanced water" is used to describewater that is neither corrosive nor prone to scaleformation.The function of the POOLCHECK is to test forthese water properties. The POOLCHECKcomprises all the components required fordetermination of free chlorine, pH value, calciumhardness, total alkalinity and, optionally, aciddemand and cyanuric acid.All the above testers, determinations, ranges andrefill packs are listed on the following two pages.Highlights. fast • accurate • simple. ready to use.
